Priority value:
10 means the switch adopts automatic numbering
5 means the switch adopts manual numbering
Manual numbering has a higher priority than automatic
numbering.
Fabric port
In a ring topology structure, the left and right ports of all units
are connected, and are displayed as Left/Right.
In a bus topology structure, the units at both ends of the bus
have only one fabric port connected, displayed as Left/ or
/Right.
Indicates that the switch adopts automatic numbering or manual
